The builder has this convoluted `while` loop which just replicates
`readlink -e`. I'm sure there was a reason at one point, because the
loop has been there since time immemorial. It kept getting copied
around, I suspect because nobody bothered to understand what it actually
did.
Incidentally, this fixes#17513, but I have no idea why.
We currently only allow upstream's default of "reboot.target" due to the
way the symlinks are initialized. I made this configurable similar to the
default unit.
This reverts commit c69c76ca7e.
This patch was messed up during a rebase -- the commit title doesn't match what
it really does at all (it is actually a broken attempt to get LUKS passphrase
prompts in Plymouth).
A disabled systemd service with a "startAt" attribute, like this:
systemd.services.foo-service = {
enable = false;
startAt = "*-*-* 05:15:00";
...
};
will cause the following errors in the system journal:
systemd[1]: foo-service.timer: Refusing to start, unit to trigger not loaded.
systemd[1]: Failed to start foo-service.timer.
Fix it by not generating the corresponding timer unit when the service
is disabled.
Previously, the value from stdenv.platform.kernelDTB was used. That
doesn't work well if both kinds (DTB and non-DTB) of generations exist
in the system profile.
':' is currently used as separator in /boot/grub/state for the list of
devices GRUB should be installed to. The problem is that ':' itself may
appear in a device path:
/dev/disk/by-id/usb-SanDisk_Cruzer_20043512300546C0B317-0:0
With such a path, NixOS will install GRUB *every* time, because it
thinks the configuration differs from the state file (due to the wrong
list split). Fix it by using ',' as separator.
For existing systems with GRUB installed on multiple devices, this
change means that GRUB will be installed one extra time.
This allows setting options for the same LUKS device in different
modules. For example, the auto-generated hardware-configuration.nix
can contain
boot.initrd.luks.devices.crypted.device = "/dev/disk/...";
while configuration.nix can add
boot.initrd.luks.devices.crypted.allowDiscards = true;
Also updated the examples/docs to use /disk/disk/by-uuid instead of
/dev/sda, since we shouldn't promote the use of the latter.
